At the beginning of the press conference, Dr. Cui Baoqiu, Vice President of Millet Group and Chairman of Technical Committee of Millet Group, reviewed Millet first.Mobile phoneProgress in the field of efficient charging. For wired charging, following the QC 2.0/3.0 certification supported by Millet 3 and Millet 5, Millet 9 launched 27W fast charging, and demonstrated the 100W super fast charging technology filled with 4000 mAh batteries for 17 minutes.
In terms of wireless charging, millet's leading advantage is more obvious. Millet MIX 2S is the first national brand mobile phone to support wireless charging, while Millet 9s 20W Wireless Flash charging is still the industry's highest power wireless charging solution, and Millet also has a variety of wireless charging.partsFor example, wireless charging treasure and wireless car charging will further bring wireless charging into the field of mass consumption.
After that, Xiaomi announced that 30W super wireless flash charging includes four major technological innovations, including the efficient direct charging architecture using Charge Turbo2.0 technology, the super high power wireless reverse charging with the highest power 7 protection in the industry, and the more secure and stable dual frequency transmission technology with stronger expansibility.30W super wireless flash charging includes four major technological innovations, including the high efficiency direct charging architecture using technology, the super power wireless reverse charging with the highest power 7 protection in the industry, and the more secure and stable dual frequency transmission technology. And the combination of wired OTG reverse charging and high power wireless reverse charging combination of universal charging combination.
Among them, the new high-efficiency direct charging architecture uses 4:1 two-stage charge pump to reduce the voltage. Compared with the previous 2:1 direct charging architecture of 20W wireless charging, it further improves the charging efficiency and reduces the heating during charging. It is the best direct charging architecture of single-core solution at present. In the demonstration stage, Millet 30W super Wireless Flash charging can achieve 4000 mAh battery 25 minutes wireless charging 50%, 69 minutes to 100%.
High-power wireless reverse charging uses BOOST combined with 1:2 reverse charge pump double boost to achieve the highest 10W reverse charging power, which is twice the 5W reverse charging power scheme on the market. At the same time, 7 protective measures such as overcurrent and overvoltage are added to ensure the safety and reliability of wireless reverse charging.
Compared with the original Qi standard data and power transmission protocol, the new dual-frequency transmission technology separates power transmission from data communication, uses Bluetooth function of mobile phone to transmit data, greatly reduces the outage phenomenon in wireless charging, improves the stability of wireless charging, and can also provide information such as time and electricity. Transfer to charging equipment.
The universal charging combination combined with wired OTG reverse charging and high power wireless reverse charging can be charged at any time, casually and arbitrarily. For example, while wired and fast charging, the phone recharges another device that supports wireless charging, such as mobile phone, headphone, etc., or the phone supplies power to other devices via wired OTG when wireless flash charging. High-speed wired high-speed wireless high-power reverse charging together constitutes the future 5G era of "triple fast charging".
Millet said that the upcoming version of Millet 9 Pro 5G will take the lead in carrying 30W super Wireless Flash charging and triple fast charging technology. In Millet's view, the arrival of 5G era will further promote wireless transmission mode. In the next year, efficient wireless charging will also become the trend of the industry. Especially, it will become the standard of high-end flagship mobile phones. Even the real high-end flagship will be equipped with "triple fast charging". That is to say, it will support high-speed wired, high-speed wireless and high-speed. Wireless reverse charging.
At the end of the conference, Millet said that the 40W high-efficiency wireless fast charging technology with higher power has entered the testing stage. At present, millet is the drafting member of the two national standards of wireless charging, and the member of WPC Wireless Charging Alliance Full Members has obtained dozens of core technology patents in the field of wireless charging. Millet will unite its Mijia Smart Home and several partners to form a full-scene wireless charging alliance to promote wireless charging at home. Travel, accommodation, catering and other scenarios cover, so that users can feel the convenience of wireless charging at any time and anywhere, further accelerate the evolution of wireless charging, enabling the 5G era.
